Description

Technical Field

[0001] This utility model relates to the field of ink raw material formulation technology, and in particular to a mixing structure for printing ink. Background Technology

[0002] Uniform mixing of printing inks is a core element in ensuring printing quality. Especially in high-speed printing processes, the dispersion stability of ink raw materials directly affects the color consistency and adhesion of the finished product. A printing ink mixing structure is a key piece of equipment for ink preparation, and its performance directly determines the rheological properties and printability of the ink.

[0003] Currently, the industry generally uses single-shaft stirring mixing equipment. Its technical principle is to drive the central shaft of the motor to rotate a single stirring paddle, and use the shear force of the paddle to achieve the initial mixing of raw materials. A static mixer is added to the equipment to assist in dispersion, or a centrifugal discharge valve is installed at the bottom of the tank. This type of structure relies on the turbulent effect of mechanical rotation, and the mixing process mainly occurs in the area near the paddle.

[0004] However, traditional single-shaft stirring structures have significant drawbacks. The stirring blind zone leads to material stratification and residue on the inner wall. Furthermore, the unidirectional rotating blades cannot cover the edge area of ​​the tank, and high-viscosity inks are prone to forming a deposition layer on the side wall of the shell. At the same time, the lack of a dynamic wall scraping mechanism causes the residual material to gradually harden and clump together, which not only reduces the mixing uniformity but also forces the equipment to be stopped frequently for cleaning, severely restricting production efficiency. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a mixing structure for printing ink, which aims to improve the problems of raw material stratification and easy residue on the inner wall caused by the stirring blind zone.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mixing structure for printing ink, comprising a housing, an inlet cover provided on the upper surface of the housing, a connecting block fixedly connected to the upper surface of the housing, a stirring assembly provided inside the housing, a connecting pipe fixedly connected to the lower surface of the housing, and an outlet assembly provided below the connecting pipe;

[0007] The stirring assembly includes two stirring rods and a transmission rod. The outer walls of the two stirring rods are rotatably connected to the inner wall of the housing, and stirring blades are fixedly connected to the outer walls of the two stirring rods. The outer wall of the transmission rod is rotatably connected to the inner wall of the housing, and a scraper is fixedly connected to the outer wall of the transmission rod. A drive assembly is provided inside the connecting block.

[0008] Furthermore, the discharge assembly includes a discharge pipe disposed below the connecting pipe, a filter plate disposed between the discharge pipe and the connecting pipe, the discharge pipe and the connecting pipe being connected by a long sliding rod, a short sliding rod being fixedly connected to the lower surface of the connecting pipe, the short sliding rod being disposed inside the discharge pipe, and a discharge valve being fixedly connected to the lower surface of the discharge pipe.

[0009] Furthermore, a slot is provided at one end of the outer wall of the long slide rod, and an irregularly shaped locking rod is rotatably connected inside the discharge pipe. The irregularly shaped locking rod is engaged with the slot, and a push block is slidably connected inside the discharge pipe. A button is slidably connected to the outer wall of the push block.

[0010] Furthermore, a spring is sleeved on the outer wall of the push block, one end of the spring is fixedly connected to the inner wall of the discharge pipe, and the other end of the spring is fixedly connected to the outer wall of the push block.

[0011] Furthermore, a second spring is provided inside the discharge pipe. One end of the second spring is fixedly connected to the outer wall of the irregular-shaped clamp, and the other end of the second spring is fixedly connected to the inner wall of the discharge pipe.

[0012] Furthermore, the drive assembly includes a first gear, a second gear, and a motor. The first gear is disposed inside the connecting block, the second gear is disposed inside the connecting block, and the motor is disposed on the upper surface of the connecting block.

[0013] Furthermore, gear one and gear two are meshed and connected, the motor output end is fixedly connected to the inner wall of gear one through the connecting block, and one end of the outer wall of the transmission rod is fixedly connected to the inner wall of gear two.

[0014] Furthermore, a first pulley is provided inside the connecting block, and a second pulley is provided inside the connecting block. The first pulley and the second pulley are connected by a belt. The inner wall of the first pulley is fixedly connected to one end of the outer wall of the stirring rod, and the inner wall of the second pulley is fixedly connected to one end of the outer wall of another stirring rod.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, the motor drives pulley one and pulley two to rotate the two stirring rods synchronously, so that the stirring blades perform double shearing and breaking down the ink raw materials, reducing the stratification phenomenon. The transmission rod driven by gear one and gear two runs in opposite directions, driving the scraper to rotate closely against the inner wall of the shell, scraping off residual raw materials in real time, reducing the risk of clumping and reducing the number of cleaning times and time.

[0017] In this utility model, a spring-lock valve structure is adopted. By pressing the button, the push block is pushed to compress the first spring, causing the irregularly shaped locking rod to disengage from the slot of the long slide rod. The discharge pipe moves down to release the filter plate lock, making it convenient to replace the filter plate. After releasing the button, the second spring automatically resets and locks, fixing the filter plate and forming a sealed structure to prevent leakage. After the ink is filtered by the filter plate, it is discharged through the discharge valve, which can initially filter impurities in the ink. Attached Figure Description

The two stirring rods rotate in the same direction to form a strong shear flow, and the transmission rod 12 runs in the opposite direction to drive a wall scraping mechanism. The outer walls of both stirring rods 10 are rotatably connected to the inner wall of the housing 1. Both stirring rods 10 have stirring blades 11 fixedly connected to their outer walls to disperse and aggregate raw materials, enhancing mixing efficiency. The outer wall of the transmission rod 12 is rotatably connected to the inner wall of the housing 1, ensuring that the scraper 13 covers the inner wall of the housing 1. The scraper 13 is fixedly connected to the outer wall of the transmission rod 12 to remove residue from the inner wall. A drive assembly is installed inside the connecting block 3. The discharge assembly includes a discharge pipe 15, which is located below the connecting pipe 14. A filter plate 16 is installed between the discharge pipe 15 and the connecting pipe 14. The filter plate 16 can be replaced with different mesh sizes to adapt to the production of various inks. The discharge pipe 15 and the connecting pipe 14 are connected by a long slide rod 18, which limits the horizontal position of the filter plate 16 to ensure a seal. A short slide rod 19 is fixedly connected to the lower surface of the connecting pipe 14 and is inserted into the discharge pipe. 15 guides the filter plate 16 to prevent misalignment during installation. A short slide rod 19 is installed inside the discharge pipe 15. The double rods work together to achieve quick positioning and installation of the filter plate 16. A discharge valve 17 is fixedly connected to the lower surface of the discharge pipe 15. A slot 20 is opened at one end of the outer wall of the long slide rod 18. A special-shaped locking rod 24 is rotatably connected inside the discharge pipe 15. The inclined design of the special-shaped locking rod 24 achieves one-way locking. It automatically disengages when pressed to unlock. The special-shaped locking rod 24 engages with the slot 20. A push block 22 is slidably connected inside the discharge pipe 15. The push block 22 converts the linear motion of the button 21 into the rotational motion of the special-shaped locking rod 24. The button 21 is slidably connected to the outer wall of the push block 22. A spring 23 is sleeved on the outer wall of the push block 22. The spring 23 provides a reset force. It automatically locks after the button 21 is released. The filter plate 16 has one end of spring 23 fixedly connected to the inner wall of the discharge pipe 15, and the other end of spring 23 fixedly connected to the outer wall of the push block 22. A second spring 25 is installed inside the discharge pipe 15, maintaining the normally closed state of the irregularly shaped locking rod 24 to ensure locking. One end of spring 25 is fixedly connected to the outer wall of the irregularly shaped locking rod 24, and the other end is fixedly connected to the inner wall of the discharge pipe 15. The drive assembly includes gear 8, gear 9, and motor 4. The gear set enables the transmission rod 12 to rotate in the opposite direction, forming convection with the stirring blade 11. Gear 8 is located inside the connecting block 3 and is directly connected to the motor 4, serving as the main drive gear. Gear 9 is located inside the connecting block 3, and motor 4 is located on the upper surface of the connecting block 3.

The inner wall of pulley 5 is fixedly connected to one end of the outer wall of stirring rod 10, and the inner wall of pulley 6 is fixedly connected to one end of the outer wall of another stirring rod 10.

[0028] Working principle: When this printing ink mixing structure is needed, first open the feed cover 2 to inject ink raw material into the housing 1 and seal it. Then start the motor 4 to drive the gear 8 in the connecting block 3 to rotate. Gear 8 meshes with gear 9 to drive the transmission rod 12 to rotate in the opposite direction. At the same time, gear 8 drives pulley 6 through belt 7 via pulley 5, so that the two stirring rods 10 rotate synchronously. The stirring blades 11 apply bidirectional shearing force to the raw material to eliminate stratification. The transmission rod 12 drives the scraper 13 to scrape off the residue against the inner wall of the housing 1. When replacing the filter plate 16, press button 21. Pushing push block 22 compresses spring 1 23, causing the irregularly shaped clamping rod 24 to disengage from the slot 20 of the long slide rod 18. The discharge pipe 15 descends, releasing the filter plate 16 from locking. After replacing the filter plate 16, push the discharge pipe 15 up and release button 21 to allow spring 2 25 to push the irregularly shaped clamping rod 24 back to lock the slot 20. Spring 1 23 pushes push block 22 back to lock, ensuring a seal. Short slide rod 19 slides within the discharge pipe 15, guiding and locking the filter plate 16. When discharging, open discharge valve 17. Ink flows into discharge pipe 15 through connecting pipe 14, is filtered by filter plate 16 to remove impurities, and is discharged from discharge valve 17.
